Hey, just wanted to give a update on tires...I have a voltage 3200 with Mastercraft power towing E rated tires in it. Decided to change them to 14 ply G rated 110 psi Sailun S637 tires ... Thanks goes out to Tanman for the advice that they would fit and they did. When the shop pulled the last of the old tires ... There was already a bubble forming.... I probably did not have more than 40 miles before a imminent blow out. Taking the rig out this weekend and will let you know how the new tires work. Yes I did luck out... The stock rims I had were stamped for 3960lb.
